Abstract

The Museum of Archaeology D. Diogo de Sousa in Braga has in its Permanent Exhibition collections of inorganic nature. Amongst these materials, the alloys are the most sensitive to environmental conditions. In order to verify the conditions in which the materials were acclimatised, between 2008 and 2011, the records of both Temperature (T°) and Humidity (HR) were analysed. In the showcases the material diversity of objects determines the levels of moisture presented. The seasonality of the environmental conditions was verified and it has been possible to confirm more constant values for Temperature (T) than for HR%, less regular. As the values shown are median the collection of metals is in good condition.
